in C for STM32F446RE microcontroller Write a source library that contains the with the following public functions: void keypadInit(void); /Initiallized the GPIO to read the keypad. uint16_t readKeypad(void); //Returns the state of all of the keypad buttons in the return value at the moment the function is called. void decodeKeypad(uint16_t, char *); //Takes the state of the keypad and returns (by reference) an array of the key's pressed.

Half solve questions: Mutual Exclusion: Mutex is an abbreviation for Mutual Exclusion. It is a programme object that prevents multiple users from accessing a shared resource at the same time. When a process accesses a shared variable, it is said to be in the critical section. When no two processes are present in the critical section at the same time, this is referred to as Mutual Exclusion or Mutex. while (true) { semaphore sem = S; while (S <= 0) do no operation { S = S-1; wait (S); } /*critical section*/ while (S > 0) { S = S+1; signal (S); } /*remainder section*/ }

Purpose of this assignment: To allow student to be able to implement a Java thread-based application by loading allowing user to perform a computation operation. Instruction: This is an individual assignment. You have to use Java thread to write a program that can perform two calculation functions concurrently. One of the function will generate a series of Fibonacci number sequence. The second function will calculate the result of factiorial function. This factorial function will allow the user to input a start number, end number and number of threads. Then, function will split into thread to perform the calculation. At the end, the function will merge the result of each thread calculation and display the result.
Language: C++ Design and write an object oriented program for the computation of the volume of boxes (having a height, a width and a depth as double values). Your solution should have methods for setting and getting the height, the width and the depth of a box as well as constructors (a default con- structor and one which sets the data members), a copy constructor and a destructor. files testbox.cpp, Box. cpp and Box.h. The program testing your code (testbox.cpp) should do the following: Name your a) Enter from the keyboard the a value for n, the number of boxes that will be entered. b) Dynamically create an array of 2*n boxes. c) Enter from the keyboard the height, width and depth of each box one after the other for the first n boxes and the add their copies on the remainder n positions (in the same order). Use the copy constructor for doing this. d) Loop across all boxes, calculate and print on the screen the volume of each box. You can assume that the input will be valid.

Simulate an Elevator-Controller Program in C programming language. The Elevator should be able to travel between five floors namely Ground, 1st, 2nd, 3rd, 4th and 5th floors. The elevator can travel going up (unless they are at the 5th floor) or going down (unless they are at the ground floor). The elevator can only containone passenger (which is the current user of the program). Initially the elevator begins and loads at the Ground Floor. If the user wants to travel to the 5th floor, the elevator shall go up to the saidfloor. It is the option of the user if they want to alight the elevator or not on the 5th floor or anyfloor on the way.Realistic rules should apply: If the user alights at the 4th floor, when they ride the elevator again, it should begin traveling from the 4th floor and from there choose to go up or down. It should have some validation,meaning, only the valid characters should be received by the program(G, 1, 2, 3, 4, 5). If the user keys-in “A” or “-1”, the program…
Covert Program in C++ import java.util.Scanner; public class Main{ public static void main(String args[]) { Scanner in = new Scanner(System.in); System.out.print("Enter Area of Circle: "); double area = in.nextDouble(); double r = Math.sqrt(7 * area / 22); System.out.print("Radius of Circle = " + r); }}
A counter variable is normally used in a program to keep track of the current count value.Create your own counter data type which is able to perform common counter operations such as increment (by one) the counter value and decrement (by one) the counter value. It is also able to set the counter to a specific value and to retrieve the counter value. The minimum value the counter can attain is zero, while the maximum value attained is stored in attribute maxValue. The class should have the following private members (attributes): (first picture) In the main program, test the workablity of your member functions by first setting an initial value to the counter. Display this value before proceeding. Then test other functions by randomly incrementing and decrementing the object’s value. Be sure to keep track of your actions. At the same time you should also make sure that your minimum value should not be less than zero. Once this is reached you will not be allowed to do further decrements.…
